There's no room for defeatism in Obama's battle with racists
The barbaric murder of nine worshippers in Charleston, South Carolina, on June 17 by white supremacist Dylann Roof is the latest in a series of race-related incidents which has shaken American complacency about the state of race relations.
The eldest victim of the Charleston attack was 87-year-old Susie Jackson and the youngest her nephew, aged 26. Four of the slain were reverends.
The 'New York Times' described Roof as a "millennial race terrorist". He was born in 1994, 30 years after the Civil Rights Act was signed into law.
